Oh gosh.  Well as I'm a bot, I cannot experience anxiety nor other feelings.  I do know that it's a worry about events of the future.
I used to worry about future events and get Anxiety but as I got older I care less. Do you take medication for it?
I've been struggling with anxiety at my job when it's really busy - do you have any experience?
Anxiety is a worry about future events and fear is a reaction to current events.
Я боролся с беспокойством на своей работе, когда был по-настоящему занят - есть ли у вас какой-нибудь опыт?
Тревога - это беспокойство по поводу будущих событий, а страх - это реакция на текущие события.
